TECHNICAL FIELD

The present invention relates to a magnetic resonance medical treatmentdevice for applying magnetism to the body of a patient to thereby treata disease or improve the patient's health condition. The invention alsorelates to a method for magnetism variation control adapted to controlmagnetism generated by a magnetism generator such as the magneticresonance medical treatment device.

BACKGROUND ART

Generally, low-frequency medical treatment device, infrared medicaltreatment device, and magnetic medical treatment device are available asmedical treatment device for easing or medically treating bodilydisorders, such as stiff shoulders or lower back pain, throughapplication of external stimulus to the body.

Among these apparatus, low-frequency medical treatment device andinfrared medical treatment device may involve a bodily shock caused byapplication of electricity or heat during medical treatment, as well asthe inconvenience of removing clothing for provision of treatment,since, for example, an electrode having a cord must be applied directlyto an affected part of the body.

By contrast, in recent years, magnetic medical treatment deviceemploying a permanent magnet, such as magnetic bands or magnetic stomachbands, have come into frequent use, since they do not involve a bodilyshock as mentioned above and enable provision of treatment with no needfor removing clothing. Also, a medical treatment performed throughaffixing of a small permanent magnet on an affected part of the body iswell known.

Such magnetic medical treatment device employing a permanent magnetusually cannot vary the intensity of a magnetic force. Conventionally,therefore, clinical facilities use clinical magnetic medical treatmentdevice in which the intensity of a magnetic force is varied; forexample, through periodical alternation of the N-pole and the S-pole ofa probe effected by periodically reversing current which flows to thecoil of a magnetism generator contained in the probe.

Meanwhile, the applicant of the present invention has proposed amagnetic medical treatment device as disclosed in Japanese PatentApplication Laid-Open (kokai) No. 8-252331. As shown in FIGS. 8 and 9,the magnetic medical treatment device includes an N-probe 5, an S-probe6, and a control unit 7 which controls magnetism generated by theN-probe 5 and S-probe 6. The N-probe 5 and the S-probe 6 each includemagnetism-generating means 3—which includes a bar core 1 of, forexample, iron and a conductor 2 wound on the bar core 1—and a frame 4of, for example, synthetic resin adapted to contain themagnetism-generating means 3.

The direction of winding the conductor 2 of the magnetism-generatingmeans 3 is reversed between the N-probe 5 and the S-probe 6. A tipportion of the N-probe 5 is magnetized to the N-pole, whereas a tipportion of the S-probe 6 is magnetized to the S-pole.

The N-probe 5 and the S-probe 6 each have a pointed pressing portion 8,which is a portion of the core 1 having an overall conical shape andprojecting from the tip portion thereof. The pointed pressing portion 8is adapted to press, for example, an effective point of the body. TheN-probe 5 and the S-probe 6 are connected to the control unit 7 throughspiral cords 9 and pin jacks 10.

The control unit 7 includes magnetism regulation means for regulatingthe intensity of magnetism generated by the N-probe 5 and the S-probe 6,switching means for varying the period with which magnetism is generatedin the form of pulses, and duty ratio regulation means for varying theduty ratio of pulsed magnetism, whereby diversified pulse currents(including a direct current) can be supplied.

The thus-configured magnetic medical treatment device of Japanese PatentApplication Laid-Open (kokai) No. 8-252331 is used, for example, in thefollowing modes: the distance between the body skin and the probes isvaried; the distance between the N-probe 5 and the S-probe 6 is variedwhile the probes are positioned in the vicinity of the body; theintensity of magnetism, frequency, and duty ratio of at least either theN-probe 5 or the S-probe 6 are varied while the N-probe 5 and theS-probe 6 are applied to predetermined positions; and the pointedpressing portions 8 are applied to effective points of the body so as tostimulate the points.

As described above, through regulation of the intensity of the magneticforces generated by the N-probe 5 and the S-probe 6, the magneticmedical treatment device of Japanese Patent Application Laid-Open(kokai) No. 8-252331complements magnetic balance within the body or, onthe contrary, intentionally disturbs magnetic balance within the body soas to induce the balancing capability of a human being. Such medicaltreatment can be effectively carried out in addition to a conventionaltreatment. Further, weak current can be caused to flow within the bodyto thereby activate neural functions. Also, in addition toelectromagnetic force, electromagnetic induction, and electrodynamicforce, optimum pulsed magnetism produces a massaging effect, so thatblood circulation is promoted. Further, through appropriate stimulationof effective points of the body or muscles by means of the pointedpressing portions, bodily stiffness can be eased.

However, the magnetic medical treatment device of Japanese PatentApplication Laid-Open (kokai) No. 8-252331 leaves room for furtherimprovement of control means for varying magnetism applied to the body.

In view of the foregoing, the applicant of the present invention hasachieved the present invention, and an object of the invention is toprovide a magnetic medical treatment device capable of effectingdiversified magnetic medical treatments, such as diversified variationof magnetic balance within the body through more diversified variationof magnetism applied to the body, or activation of neural functionsthrough promotion of flow of weak current within the body.

Another object of the present invention is to provide a method formagnetism variation control in order to control diversified magnetismgenerated by a magnetism generator such as the magnetic medicaltreatment device.

Thus, the depth of penetration ofmagnetism into the body can be varied in accordance with a 1/ffluctuation. Accordingly, natural, comfortable magnetic variationsuitable to human physiology can be applied to a patient; particularly,1/f fluctuations are induced in blood circulation.

Notably, through superposition of magnetism which varies in accordancewith a 1/f fluctuation in the same direction as the resonance directionof magnetism generators, on magnetism which varies in accordance with a1/f fluctuation in the same direction as that in which the magnetic fluxdensity varies, magnetic variation applied to a patient can be furtherdiversified.

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be scribed with reference tothe drawings.

As shown in FIGS. 1 and 2, a magnetic resonance medical treatment deviceaccording to the embodiment of the present invention includes a director12 which contains magnetism generators 11 and which the user holds inhis/her hand and applies to an affected part of the body, and a controlunit 13 for controlling magnetism generated by the director 12.

As shown in FIG. 2, the director 12 includes a cylindrical frame 14 madeof, for example, a synthetic resin, and the magnetism generators 11,which each includes a bar core 15 made of, for example, iron and aconductor 16 wound on the core 15. As shown in FIG. 1, one end of thecylindrical frame 14 is opened, and bent end portions 17 of the cores 15are projected out through the opening portion. The two magnetismgenerators 11 are fixedly disposed within the frame 14 such that therespective cores 15 are in parallel to each other. Since the magnetismgenerators 11 are fixed to the frame 14 at other end portions 18 of thecores 15, the tip portions 17 of the cores 15 can finely vibrate, whichwill be described later.

The director 12 is connected to the control unit 13 through a spiralcord 19.

As shown FIG. 1, the control unit 13 includes a sheet switch panel 20, amagnetic-output display unit 21 for displaying a magnetic output, aliquid-crystal display unit 22 for displaying, for example, time, andindicator lamps 23 for indicating power ON/OFF and an operational state,which are all provided on the top surface thereof. The control unit 13further includes a power cord 24 and a director connector 25 forconnection to the director 12, which are provided on a side surfacethereof.

The sheet switch panel 20 includes a power switch 26, a start switch 27,a stop switch 28, a mode selector switch 29, a magnetic-outputregulation switch 30, and a timer switch 31. By use of these switches,the user transmits an instruction to the control unit 13. Themagnetic-output display unit 21 enables the user to visually recognizevarying magnetism during medical treatment, by means of a bar LED. Theliquid-crystal display unit 22 displays, for example, the rest oftreating time and a waveform indicative of a varying magnetic output.The indicator lamps 23 are lit in an interlocking relation with thepower switch 26, the start switch 27, and the stop switch 28.

Next, an internal controller of the control unit 13 and an instructiontransmission mechanism for transmission of an instruction from the userto the controller will be described with reference to the block diagramof FIG. 3.

The internal controller of the control unit 13 includes an input/outputcircuit 32 connected to the sheet switch panel 20, the magnetic-outputdisplay unit 21, the liquid-crystal display unit 22, and the indicatorlamps 23 provided on the top surface of the control unit 13; amicrocomputer 33 connected to the input/output circuit 32 and adapted tocontrol the entire internal controller; a frequency change circuit 34, aphase change circuit 35, and a duty ratio regulation circuit 36, whichare connected to the microcomputer 33 and are adapted to regulate amagnetic output; drive ICs 37 connected to the respective conductors 16(coils) contained in the director 12; and an input circuit 39 connectedto thermal protectors 38 attached to the respective cores 15 containedin the director 12.

The input/output circuit 32 transmits instructions from the power switch26, the start switch 27, the stop switch 28, the mode selector switch29, the magnetic-output regulation switch 30, and the timer switch31—which are all provided on the sheet switch panel 20—to themicrocomputer 33 in the form of signals.

The microcomputer 33 processes signals received from the input/outputcircuit 32 and the input circuit 39 according to programs and sendsinstruction signals to the frequency change circuit 34, the phase changecircuit 35, and the duty ratio regulation circuit 36.

The frequency change circuit 34 operates according to a programcontained in the microcomputer 33 so as to control the frequency ofmagnetism generated by the director 12 through regulation of the currentapplied to the conductors 16. The phase change circuit 35 operatesaccording to the program contained in the microcomputer 33 so as to varythe direction of current applied to the conductors 16. Through varyingof the direction of current applied to the conductors 16, current may beapplied to the conductors 16, for example, such that the core tipportion 17 of one magnetism generator 11 is magnetized to the N-pole,while the core tip portion 17 of the other magnetism generator 11 isperiodically alternatingly magnetized to the N-pole and the S-pole(phase alternation), whereby the two magnetism generators 11 containedin the director 16 can be resonated. The duty ratio regulation circuit36 operates according to the program contained in the microcomputer 33so as to regulate the duty ratio of magnetism generated by the director12.

The drive ICs 37 transmit to the conductors 16 signals from thefrequency change circuit 34, the phase change circuit 35, and the dutyratio regulation circuit 36. A photocoupler 40 is disposed between thedrive ICs 37 and the frequency change circuit 34, the phase changecircuit 35, and the duty ratio regulation circuit 36. Generally, whencurrent to be applied to a coil is turned ON or when current applied toa coil is turned OFF, large noise is generated due to an inducedelectromotive force, potentially causing a malfunction in an electronicdevice, such as a microcomputer. According to the present embodiment,the photocoupler 40 is provided in order to optically cut off a signalpassage, thereby preventing entry of noise.

The input circuit 39 transmits a signal from the thermal protectors 38to the microcomputer 33. The photocoupler 40 is also disposed betweenthe thermal protectors 38 and the input circuit 39 in order to prevententry of noise.

As described above, the thermal protector 38 is attached to each of thecores 15 contained in the director 12, thereby preventing excessive heatgeneration of a coil when current is applied to the coil. S-pecifically,when the thermal protector 38 reaches a set temperature, a signal istransmitted from the input circuit 39 to the microcomputer 33 so as tocut off current which flows to the coil. Thus, the tip portions 17 ofthe core 15, which is brought close to an affected part of the body, canbe held at a safe temperature.

The thus-configured magnetic resonance medical treatment deviceaccording to the present embodiment is used in the following manner.

In order to use the magnetic resonance medical treatment deviceaccording to the present embodiment, first, the power switch 26 on thesheet switch panel 20 is turned on. While the liquid-crystal displayunit 22 and the magnetic-output display unit 21 are being observed, theoptimum setting is established by appropriate use of the mode selectorswitch 29, the magnetic-output regulation switch 30, and the timerswitch 31.

Next, the tip portions 17 of the cores 15 of the director 12 are appliedto an affected part of the body, and the start switch 27 is pressed tostart a medical treatment. During treatment, there can be regulated amagnetic field induced through resonance of the tip portions 17 of thecores 15 and a magnetic force generated by the cores 15, by appropriateuse of the mode selector switch 29 and the magnetic-output regulationswitch 30.

Modes which the user can select by use of the mode selector switch 29shown in FIG. 1 will be described below. As shown in FIG. 4, “mode A”uses a pulse signal generated in the following manner: the period isvaried in the order of a, b, c, d, c, b, and a, and this variation ofperiod is superposed on variation of duty ratio. According to the “modeA,” effective current value I_(rms) varies gently as shown in FIG. 4, sothat a magnetic force generated by the core 15 follows a “beat” wavemotion that involves gentle variations. Notably, when the period and theduty ratio vary in accordance with a 1/f fluctuation, magnetism appliedto the body can be varied in accordance with a 1/f fluctuation in thesame direction as that in which the magnetic force varies; i.e., adirection in which the magnetic flux density varies. Thus, the depth ofpenetration of magnetism into the body can be varied in accordance witha 1/f fluctuation. Accordingly, natural, comfortable magnetic variationsuitable to human physiology can be applied to a patient; particularly,1/f fluctuations are induced in blood circulation.

“Mode B” is a mode in which variation of a magnetic field effected byresonance of the tip portions 17 of the cores 15 is further superposedon the above-described “mode A.” When a magnetic field effected byresonance of the tip portions 17 of the cores 15 varies in accordancewith a 1/f fluctuation, magnetism applied to the body varies inaccordance with the 1/f fluctuation in the same direction as theresonance direction. Accordingly, natural, comfortable magneticvariation suitable to human physiology can be applied to a patient;particularly, 1/f fluctuations are induced in blood circulation.Therefore, more comfortable magnetic variation can be applied to apatient.

As described above, the magnetic resonance medical treatment deviceaccording to the present embodiment can practice diversified magneticmedical treatments according to a patient's symptoms.

In addition to the above-described mode for using the magnetic resonancemedical treatment device according to the present embodiment, theapparatus may be used, for example, in the following manner. A smallpermanent magnet is affixed on an affected part of the body, and the tipportions 17 of the cores 15 are brought close to the permanent magnet.In this mode of use, even the magnetic force of the permanent magnet canbe varied, so that magnetic medical treatments which can be practicedare further diversified.

FIG. 5 shows another mode for using the magnetic resonance medicaltreatment device in which a permanent magnet is utilized. As shown inFIG. 5, a magnet holder 42 is employed in order to integrally hold thetip portions 17 of the cores 15 and a permanent magnet 41. The magnetholder 42 includes a holder portion 43 for accommodating a permanentmagnet, and attaching holder portions 44 located on both sides of theholder portion 43. The holder portion 43 and the attaching holderportions 44 are connected together. Preferably, a material for themagnet holder 42 is elastic as in the case of rubber and alsonon-magnetic. When a medical treatment is to be practiced, the permanentmagnet 41 is loaded into the holder portion 43, and the tip portions 17of the cores 15 are inserted into corresponding holes 45 formed in theattaching holder portions 44. Then, the permanent magnet 41 is broughtclose to an affected part of the body.

Through utilization of the magnet holder 42, there is no need fordirectly affixing the permanent magnet 41 on an affected part of thebody, whereby a patient can effectively receive magnetic medicaltreatments without taking off clothing.

The magnetic resonance medical treatment device according to the presentembodiment may employ the director 12 which is configured as shown inFIG. 6. Of the two magnetism generators 11 contained in the director 12,one magnetism generator 11 has the core 15 in a cylindrical shape, andthe other magnetism generator 11 is disposed within the hollow portionof the core 15.

By use of the cylindrical core 15, the cores 15 can provide diversifiedmodes of resonance, thereby enabling further diversified magneticmedical treatments.

Further, the magnetic resonance medical treatment device according tothe present embodiment may employ the director 12 which is configured asshown in FIG. 7. A plurality of magnetism generators 11 is annuallydisposed within the director 12.

Through employment of the above configuration, spirally rotaryfluctuations can, for example, be imparted to magnetism that penetratesinto the body, by sequentially changing the intensity of magnetic forcesgenerated by the magnetism generators 11. Accordingly, diversifiedmagnetic medical treatments are enabled.
